EMS型高速磁浮列车导向系统的工作条件变化范围大,采用一般方法设计的控制器无法在整个工作范围内保持一致的控制性能。为了解决这个问题,研究了自适应导向控制器的设计方法。首先,建立了导向系统的数学模型,通过设计电流环使模型降阶;并分析了导向系统参数的变化原因及特性,在此基础上采用自校正的自适应控制理论,设计了参数自适应的导向控制器。仿真结果表明,该控制器较好地解决了导向系统在整个工作范围内特性不一致的问题。
EMS-type high-speed maglev train steering system has a wide range of operating conditions, the use of the general method of design of the controller can not maintain consistent control performance throughout the work area. In order to solve this problem, the design of adaptive director controller is studied. Firstly, the mathematical model of the guidance system is established, and the model is reduced by designing the current loop. The causes and characteristics of the steering system parameters are analyzed. Based on the self-tuning adaptive control theory, the adaptive parameters Guide controller. Simulation results show that the controller solves the problem of inconsistent characteristics of the guidance system over the entire working range.
